TGA1135B-SCC
Reflow process assembly notes:
•= AuSn (80/20) solder with limited exposure to temperatures at or above 300ΓC
•= alloy station or conveyor furnace with reducing atmosphere
•= no fluxes should be utilized
•= coefficient of thermal expansion matching is critical for long-term reliability
•= storage in dry nitrogen atmosphere
Component placement and adhesive attachment assembly notes:
•= vacuum pencils and/or vacuum collets preferred method of pick up
•= avoidance of air bridges during placement
•= force impact critical during auto placement
•= organic attachment can be used in low-power applications
•= curing should be done in a convection oven; proper exhaust is a safety concern
•= microwave or radiant curing should not be used because of differential heating
•= coefficient of thermal expansion matching is critical
Interconnect process assembly notes:
•= thermosonic ball bonding is the preferred interconnect technique
•= force, time, and ultrasonics are critical parameters
•= aluminum wire should not be used
•= discrete FET devices with small pad sizes should be bonded with 0.0007-inch wire
•= maximum stage temperature: 200ΓC
GaAs MMIC devices are susceptible to damage from Electrostatic Discharge. Proper precautions should
be observed during handling, assembly and test.
